Flexible Sigmoidoscopy
Flexible sigmoidoscopy is a key tool for finding early signs of colorectal cancer in the lower intestine. It’s a simple way for doctors to check the rectum and sigmoid colon. This helps spot any problems early on.
This screening is part of a bigger check-up for your lower GI tract. It helps doctors find polyps, inflammation, or other issues. These might need more tests or treatment.
In this guide, we’ll explore flexible sigmoidoscopy in detail. We’ll talk about its purpose, how to prepare, the procedure itself, and why regular screenings are important. Knowing about this test helps you make smart choices about your health and stay safe.
What is Flexible Sigmoidoscopy?
Flexible sigmoidoscopy is a way for doctors to look at the lower part of the large intestine. This includes the rectum and sigmoid colon. It’s a gastrointestinal endoscopy method used to find intestinal polyps and diagnose bowel diseases.
A thin, flexible tube called a sigmoidoscope is used. It has a light and camera. This lets doctors see the colon’s inside on a screen. The scope moves through the sigmoid colon for a detailed look.
Definition and Explanation of the Procedure
Flexible sigmoidoscopy helps find colorectal cancer early. Doctors can see the rectum and sigmoid colon’s lining. They look for polyps, inflammation, or ulcers. They might take tissue samples for more tests.
Differences Between Flexible Sigmoidoscopy and Colonoscopy
Flexible sigmoidoscopy and colonoscopy both check for intestinal polyps and bowel diseases. But they differ in what they examine:
| Flexible Sigmoidoscopy | Colonoscopy |
|---|---|
| Examines only the lower part of the colon (rectum and sigmoid colon) | Examines the entire colon |
| Usually does not require sedation | Typically requires sedation |
| Preparation involves a small enema before the procedure | Preparation involves a full bowel cleanse |
| Takes about 10-20 minutes | Takes about 30-60 minutes |
Both methods are key in finding and preventing colorectal cancer. Your doctor will choose the best one for you based on your needs and risk.
Why is Flexible Sigmoidoscopy Performed?
Flexible sigmoidoscopy is a key tool in healthcare. It lets doctors see the lower colon and rectum. This helps find and prevent many gut problems early on.
Screening for Colorectal Cancer
Flexible sigmoidoscopy is mainly used to check for colon cancer. It finds polyps, which can turn into cancer, early. This is vital for people over 50 or those with a family history of colon cancer.
| Age | Recommended Screening Interval |
|---|---|
| 50-75 years | Every 5 years |
| 76-85 years | Based on individual risk factors |
Investigating Symptoms of Gastrointestinal Disorders
It also checks for symptoms of gut problems. It helps find causes of belly pain, like diverticulitis or inflammatory bowel disease. It can also find out why someone is bleeding from their rectum, helping to spot serious issues like colon cancer.
Monitoring Inflammatory Bowel Disease
For those with Crohn’s or ulcerative colitis, it’s key. It lets doctors see how bad the inflammation is. They can then change treatments and watch for complications.
In short, flexible sigmoidoscopy is very useful. It helps find cancer, check for bleeding, and manage inflammatory diseases. It gives doctors a clear view of the lower gut, helping prevent and treat many conditions.
Preparing for a Flexible Sigmoidoscopy
Getting ready for a flexible sigmoidoscopy is key. You’ll need to stick to certain diets, do intestinal cleansings, and skip some medicines. Following these steps helps get accurate results and keeps the exam safe.
Dietary Restrictions and Cleansing Procedures
Before the exam, you’ll change your diet and clean your intestines. Here’s what you’ll do:
| Days Before Exam | Dietary Restrictions | Cleansing Procedures |
|---|---|---|
| 3-5 days prior | Low-fiber diet | N/A |
| 1-2 days prior | Clear liquid diet | Laxatives or enemas as directed |
| Day of exam | No solid foods | Additional cleansing if needed |
Your doctor will tell you how to prepare your bowels. It’s important to follow these steps well. This makes sure your colon is clean for the exam.
Medications to Avoid Before the Exam
Tell your doctor about all your medicines. Some might need to be changed or stopped before the test. Here are some to avoid:
- Blood thinners (e.g., warfarin, aspirin)
- Non-steroidal anti-inflammatory drugs (NSAIDs)
- Iron supplements
- Diabetes medications (adjustments may be necessary)
By following these steps, you help make the test a success. It will give your doctor important information.

The Flexible Sigmoidoscopy Procedure
A flexible sigmoidoscopy is an endoscopic examination that lets doctors see the lower part of the large intestine. This includes the rectum and sigmoid colon. It uses a flexible, narrow tube with a light and camera at the tip. Knowing what to expect can make you feel more comfortable.
What to Expect During the Exam
During the exam, you’ll lie on your left side on the table. The doctor will gently put the lubricated sigmoidoscope through your rectum. They will slowly move it through the lower colon.
They might use air to make the colon bigger, giving a clearer view. The camera shows images on a monitor. This lets the doctor check the lining of your intestine for any problems.
Sedation Options and Pain Management
Most people find flexible sigmoidoscopy easy to handle and don’t need sedation. But, if you’re anxious or uncomfortable, you might get mild sedation. The doctor can also give you medicine to ease cramping or bloating.
Talk to your doctor about sedation and pain relief before the exam. This way, you can choose what makes you feel most comfortable.
Duration of the Procedure
The procedural timeline for a flexible sigmoidoscopy is short, lasting 10 to 20 minutes. But, you should plan to spend more time getting ready and recovering. After the exam, you might feel a bit of cramping or bloating, but it goes away quickly.
You can usually go back to your normal activities and diet soon after.
Risks and Complications Associated with Flexible Sigmoidoscopy
Flexible sigmoidoscopy is usually safe, but there are risks and complications. Common issues include bleeding, a hole in the colon wall, and infection. But these problems are rare. Doctors take many steps to keep patients safe.
Bleeding might happen if a tissue sample is taken or a polyp is removed. Most of the time, this bleeding is minor and heals quickly. But sometimes, it can be more serious and need extra treatment. A hole in the colon wall is another risk. This is very rare, happening in less than 1 in 1,000 cases, and might need surgery.
The risk of complications with flexible sigmoidoscopy is shown in the table below:
| Complication | Incidence Rate |
|---|---|
| Bleeding | Less than 1 in 100 procedures |
| Perforation | Less than 1 in 1,000 procedures |
| Infection | Rare |
To lower risks and keep patients safe, doctors follow strict rules. They:
- Check the patient’s medical history and medicines
- Use clean equipment and methods
- Watch the patient’s vital signs during the test
- Give clear instructions after the test
It’s important for patients to talk to their doctor about any worries before the test. Knowing the risks and benefits helps patients make good choices about their health. They can work with their doctor to get the best results.
Interpreting Flexible Sigmoidoscopy Results
After a flexible sigmoidoscopy, your doctor will look at the diagnostic findings. They will decide what to do next. The results might show healthy tissue or something that needs more checking or treatment.
Normal Findings and Abnormalities
If the test shows normal results, it means the colon looks healthy. There’s no inflammation, polyps, or other problems. But, if there are abnormal results, like polyps or ulcers, you might need more tests or treatment.
Some common issues found include:
| Abnormality | Description |
|---|---|
| Polyps | Growths on the lining of the colon that can be benign or precancerous |
| Inflammatory Bowel Disease | Chronic inflammation of the colon, such as Crohn’s disease or ulcerative colitis |
| Diverticulosis | Presence of small pouches in the colon wall |
| Colorectal Cancer | Malignant growth in the colon or rectum |
Follow-up Procedures and Treatment Options
Based on the abnormal results, your doctor might suggest more tests or therapeutic interventions. These could be:
- More imaging tests, like a colonoscopy or CT scan
- Biopsy of suspicious tissue for further analysis
- Removal of polyps or abnormal growths
- Medications to manage inflammation or other symptoms
- Surgery to remove severely damaged or cancerous parts of the colon
Your healthcare provider will create a treatment plan just for you. They will use the diagnostic findings from your test. This ensures you get the best care for your needs.
Recovery After a Flexible Sigmoidoscopy
After a flexible sigmoidoscopy, recovery is quick with little post-procedure care needed. Most people can leave the hospital soon after and get back to normal in a day. But, it’s important to know about possible side effects and discomfort during recovery.
Right after, some might feel cramping, bloating, or gas from the air in the colon. These feelings usually go away in a few hours. To manage side effects, over-the-counter pain relievers like acetaminophen or ibuprofen can help. Also, passing gas can ease bloating and pressure.
Most can go back to their usual diet and activities the same day. But, if sedation was used, they should get a ride home and avoid driving or making big decisions that day. Drinking lots of water helps get rid of leftover bowel prep solution.
Potential Side Effects and Discomfort
While serious problems are rare, it’s good to know about possible side effects that might need medical help. These include:
- Persistent abdominal pain or severe cramping
- Rectal bleeding that doesn’t stop after a few hours
- Fever or chills
- Dizziness or weakness
If any of these happen, call the doctor right away for advice and treatment.
Resuming Normal Activities and Diet
Most can get back to their usual routine and diet within 24 hours. But, if polyps were taken out, the doctor might give special diet and activity rules. It’s key to follow these to heal right and avoid problems.
In the days after, watch your bowel movements closely. If you have ongoing constipation or diarrhea, tell your doctor. Knowing about recovery and side effects helps for a smooth and comfortable time after the procedure.
The Importance of Regular Colorectal Screening
Regular colorectal screening is key to preventive healthcare. It catches colorectal cancer and other gut issues early. This leads to better treatment and higher survival rates. By getting tests like flexible sigmoidoscopy, people can protect their gut health.
Risk Factors for Colorectal Cancer
Many things can raise your risk of colorectal cancer. Being over 50, having a family history, or a history of inflammatory bowel disease are some. Obesity, smoking, and eating too much red meat also play a part. Knowing these risks helps set up the right screening plan.
Recommended Screening Intervals
Guidelines say people at average risk should start screening at 45. The screening schedule varies based on the method and risk level. For flexible sigmoidoscopy, it’s every 5 years with FOBT or every 10 years without it. Those at higher risk might need more tests, as their doctor suggests.
Understanding the value of colorectal screening and following guidelines helps keep your gut healthy. It also lowers the risk of colorectal cancer. Talking to your doctor regularly ensures care that fits your needs and risk factors.
